BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a heat exchanging ventilator, and more particularly to a heat exchanging ventilator that may exchange air. Likewise, by means of the heat conductivity of air admitting and venting passageways with each other, the indoor air temperature inputted from the air admitting passageway is approximately equivalent to room temperature, thus decreasing the consumption of energy resources.

2. Description of the Prior Arts

At present, in most places, such as work places or homes, are installed with air conditioning equipments, e.g. air conditioners or heaters, for controlling room temperature at a constant temperature to obtain a comfortable environment.

However, if the indoor air circulates poorly, an uncomfortness will bring about. To improve such a problem, an improved method has been developed. For example, opening window slightly to make fresh air flows in from the outdoors, yet causing a temperature difference between the indoors and outdoors and consuming energy resources.

The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide a heat exchanging ventilator that may exchange air, and by means of the heat conductivity of air admitting and venting passageways with each other, the indoor air temperature inputted from an air admitting passageway is approximately equivalent to room temperature, thus decreasing the consumption of energy resources.

In accordance with one aspect of the present invention, there is provided a heat exchanging ventilator comprising a temperature isolating body including an air admitting passageway and an air venting passageway couplingly arranged therein and allowing to conduct heat with each other. The two ends of the air admitting and venting passageways are in communication with the indoors and outdoors, respectively, and the air admitting and venting passageways are provided at inlets thereof with suction fans, individually, so as to let fresh air to be sucked from the suction fan of the air admitting passageway, while the indoor air may be vented from the suction fan of the air venting passageway, thereby exchanging air. Likewise, by means of the heat conductivity of the air admitting and venting passageways with each other, the indoor air temperature inputted from the air admitting passageway is approximately equivalent to room temperature.

From above-mentioned descriptions, since the air admitting and venting passageways are couplingly arranged together, a progressive heat exchange in the temperature isolating body may be achieved so that the closer the fresh air in the air admitting passageway is near to the outlet of the indoors, the more similar temperature is equal to the set indoor temperature. For example, if an air conditioner is installed indoors, the temperature of the fresh air in the air admitting passageway thereof is lowered for being inputted into the indoors, yet if a heater is installed indoors, the temperature of the fresh air in the air admitting passageway is heated by the air venting passageway for being inputted into the indoors, thus decreasing the consumption of energy resources during air exchanging process.

The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

A heat exchanging ventilator in accordance with the present invention comprises a temperature isolating body 1 including an air admitting passageway 2 and an air venting passageway 3 couplingly arranged therein and allowing to conduct heat with each other (as shown in FIG. 1, the air admitting and venting passageways 2, 3 are arranged in a coupling manner. Also, the temperature isolating body 1 may include passages formed therein, and by using a heat conducting plate, the air admitting passageway 2 may be separated from the air venting passageway 3). The two ends of the air admitting and venting passageways 2 and 3 are in communication with the indoors and outdoors, respectively, and the air admitting and venting passageways 2 and 3 are provided at inlets thereof with suction fans 21 and 31, individually (as illustrated in FIGS. 2 and 3), so as to let fresh air to be sucked from the suction fan 21 of the air admitting passageway 2, while the indoor air is vented from the suction fan 31 of the air venting passageway 3, thereby exchanging air. Likewise, by means of the heat conductivity of the air admitting and venting passageways 2, 3 with each other, the indoor air temperature inputted from the air admitting passageway 2 is approximately equivalent to room temperature.

From above-mentioned descriptions, since the air admitting and venting passageways 2, 3 are couplingly arranged together, a progressive heat exchange in the temperature isolating body 1 may be achieved so that the closer the fresh air in the air admitting passageway 2 is near to the outlet of the indoors (as shown in FIG. 4), the more similar temperature is equal to the set indoor temperature. For example, if an air conditioner is installed indoors, the temperature of the fresh air in the air admitting passageway 2 thereof is lowered for being inputted into the indoors, yet if a heater is installed indoors, the temperature of the fresh air in the air admitting passageway 2 is heated by the air venting passageway 3 for being inputted into the indoors, thus decreasing the consumption of energy resources during air exchanging process.

Besides, if the air admitting and venting passageways 2 and 3 are couplingly arranged in a curved manner (as illustrated in FIG. 5), the path and time of heat conductivity may be enhanced so that the air admitting passageway 2 may input the air closer to the indoor temperature.

Furthermore, the above-mentioned air admitting and venting passageways 2 and 3 may be designed to a multi-layer and wound type (as illustrated in FIG. 6).

Also, the air admitting and venting passageways 2 and 3 may be designed to a plurality type and then combined together (as shown in FIGS. 7 and 8), wherein they are arranged in a cross-positioned manner, thereby improving a heat conducting effect.

The suction fans 21 and 31 are controlled by way of multi-step switches, respectively, such that during operation, the suction fans 21 and 31 may apply different rotating speeds to control the amount of air flowing, wherein the suction fans 21 and 31 may involve filtering structures 22 and 32 formed therein, respectively.

The suction fans 21 and 31 of the air admitting and venting passageways 2 and 3 may be attached on the same sides, for instance, they are all disposed in the indoors for diminishing damage due to exposes outside or when they are mounted outdoors, a noise problem occurring indoors may be avoidable. By virtue of the rotations of the suction fans 21 and 31, the air admission of the air admitting passageway 2 and the air exhaust of the air venting passageways 3 may be controlled. It is because that the sucking and blowing differences may result in so as to improve the air admitting and venting effect.

The temperature insolating body 1 further includes heat insulating materials wrapped on the air admitting and venting passageways 2 and 3 thereof for increasing heat conducting effect.

The invention is not limited to the above embodiment but various modifications thereof may be made. It will be understood by those skilled in the art that various changes in form and detail may made without departing from the scope and spirit of the present invention.
